Not too easy. Not too difficult.
I only recommend this course if you REALLY need to learn how to build a mobile app. Otherwise you won't need this for anything productive.
You get to learn how Android Studio software works and how to implement code to build your app. Its satisfying building an app then seeing it work on your phone when your done.

Advice for students:
The instructor doesn't know what hes doing and students would have to rely on the textbook to know what to do or use google. Since the textbook is pretty much a step by step, i would skip to ending of some steps to look at the WHOLE code and copy that.
